ya.. basically to deal with last stand, first time it might catch you offguard.. 2nd time, there is like 2-3 seconds after you kill that it takes for him to transform or w/e.  Kill him and start running like a madman   teleport works nicely as well.

To actually kill an oak beyond level 8.. this can be tricky.  Well.. it can be tricky only if he's gotten rank 3 shield.. this allows him to shield himself and teleport out without fear of interruption or death.  Most oak's don't use this until the last second.. I know I don't.  So, say you have a sedna / ub against the oak.  Work him down with spit / pounce / autoattacks, w/e you have.. try to predict how much damage you can do in 4 seconds.. then when he has that much hp left.. silence him, and grasp him right after the silence.  Technically 5 seconds.. but you might overestimate the damage you do, or cut off a second on the silence w/e.  I've thought I was being clever saving my shield til I was low.. but if timed well.. the oak better be shielding around 2500 hp or else it's good night

Oak is a very strong late game Demigod.. but that's okay because a game of Demigod is often won because of good decisions made early in the game, and then capitalizing on those decisions as you level up.

In this way, Oak is beaten in the same way most others are.  For instance, you were worried that he had a large force of grunts supporting him. If early on you can manage your flag control so you get warscore faster, you will ultimately deny him of these. Secondly, maintaining control of key flags, like a Deblitation flag, a +15% health flag, or similar can keep the early game in your favor, and may even result in some kills.

Lastly, knowing how to use mobility items in the game, especially Wand of Speed and Teleport scrolls can significantly up your game.  These will both help you run from battle, but more importantly can let you ambush someone who is not otherwise able to fight back. Early game, oak can often fall into this category as he doesn't have many good low level abilities.

Ah okay, thanks for the information I recently had a few more matches a 1 vs 1 Unclean beast vs. Oak and thoroughly demolished him. I think I was believing his damage was coming from himself, when his army was the real problem so I obtained the Semi-AOE ability for beast (the exploding corpse thing I believe) and stunned him before the teleports and it worked out nicely. Thanks for the advice, nice to know some game communites aren't full of idiots these days. WoW was a $#@%#

Also good god, does any demigod cut through people like beast? I almost feel overpowered on this thing..and I never play demigods that the community feels are overpowered because it simply kills the enjoyment of a win. Are there certain gods that everyone feels need buffed or nerfed? or is it simply "a kills b unless b specs C" situation? Thanks again.
